Divide the below grid into ten areas (blobs) so that each area:

• ... is contiguous (all cells connect via edges, not just vertices).
• ... has exactly one of the ten numbers shown in the grid.
• ... contains as many cells as the number that it contains.
• ... borders (along edges, not vertices) the same number of other areas as the number that it contains; for example, a 6-cell area will border six other areas, again based on the digit 6 that is contained within its bounds.
